I took off my stock rims and tires and added some new 35's ( with a 6" lift ) after the install I now have to reprogram the speedo and my air pressure sensor warning is on.

How do you reset the sensor. And what is everyone using to recalibrate the speedo.

Thanks

If you moved the sensors to the new wheel, you should not have to do a reset of the sensors. If they were not moved, then you either you need to move them, buy new, or live with the light.

 

As far as the speedo, I installed a chip which you can set the new tire size and automaticly calibrates your speedo. When I did my lift and tires, the shop that did the work messed up one of my sensors and installed a new one. The computer still read that my sensors had a fault. Come to find out, there is a section in your owners manual that talks about retraining your tpms. You have to have a special training tool, which is supposidly a strong magnet, to retrain each sensor. I ended up taking my truck to the service department at my nearest ford dealer and they retrained the computer FREE of charge and only took about 5 min. May want to try and do the same. If not, ive looked up the training tools online and you can find them fairly cheap if really wanted one. Good luck
